The Los Angeles class sub is tremendous, I actually got to tour the USS Honolulu during my honeymoon.  Incredible machines, I'm sure the Virginia will be amazing too.
The 688i was a great advancement, the addition of the VLS really expanded its capabilities and demonstrated the versatillity of a well designed chassis.
$900m, and worth every penny.  Wanna know why?  Watch the Hunt for Red October.
